Answer:
The expression consists of 2 factors, and each factor contains 3 terms.
You are trying to solve for k (get k by itself)
-5k - 19 = 5 - 13k Add 19 on both sides
-5k - 19 + 19 = 5 - 13k + 19
-5k = 24 - 13k Add 13k on both sides
-5k + 13k = 24 - 13k + 13k
8k = 24 Divide 8 on both sides
k = 3
The answer to the first one is A and the second one is D
